Hi,
I have understood your requirements completely and I am interested to work on these tasks.
I am experienced Android developer.
1] I understood that we need to open Instagram and Twitter app and specific user page in it.
2] I will complete these tasks as you want. And will develop dialog box to enter id in app also as required.
3] I will provide you best service with perfect communication.
Please send me a message so that we can discuss more.
Thanks,
Swapnil Chouhan
